ABSTRACT:
The invention is directed to an electrotreating apparatus, utilizing a vertical-pass electrotreating cell wherein the strip passes over a conductor roll, through one corridor of the cell, around the sink roll, up through a second corridor of the cell and over a second conductor roll. Electrolyte is caused to flow from the lower portions of each corridor, up through the corridors and overflow into a collector tank for recycle through the system. Rather than support electrodes from the top of each corridor, electrode replacement is facilitated by inserting the electrodes through the outer walls of each of the corridors. Proper sealing of such electrodes is achieved by utilizing an electrode with a T-shape cross-section, in which the top of the T is a flange for exerting a bearing, liquid-tight sealing force against the outer surface of the corridor wall, while the vertical portion of the T comprises that part of the electrode which is inserted into a hole in the corridor wall.
